Seasons and road conditions
Summer, from June to August, offers long days and, in the far north, the midnight sun. In spring and autumn, conditions vary from south to north: Skåne can be green while the mountains of Lapland are still, or already, covered in snow.
Winter rewards careful drivers with northern lights and quiet roads, but it demands respect: daylight is short, roads can be icy, and winter tyres are compulsory from 1 December to 31 March whenever there are winter road conditions. Check the road reports from the Swedish Transport Administration (Trafikverket) before each stage and keep your plans flexible.
